The value of a stock increases 1423 points twice in one week. the other three days the value decreases by 10 points, 813 points, and 1223 points. by how many points did the value of the stock change that week?

Explanation:

You need to analize the information provided in the exercise.

You know that:

1. The value of a stock increases 1,423 points twice in one week. This indicates that you must multiply 1,423 points by 2:

2. The other three days the value decreases by 10 points, 813 points, and 1,223 points. So you need to find the sum. This is:

Finally, you need to subtract 2,846 points and 2,046 points in order to calculate by how many points the value of the stock changed that week.

Therefore, the result is:

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
